The job of a power transformer in an electronic system is to provide that system with a number of ac supplies of various voltages and suitable values of current from the high voltage public electricity supply. Area a starting at the top you will notice that a transformer is feeding power to the whole system. It is used to transfer electrical energy and to increase or decrease the tension in an ac circuit keeping the frequency.
The primary transformer winding normally is used to set up current that is then transferred to one or more secondary windings of the transformer. Three phase transformer consists of three sets of primary windings one for each phase and three sets of secondary windings wound on the same iron core. Separate single phase transformers can be used and externally interconnected to yield the same results as a 3 phase unit. The primary windings are connected in one of several ways.
A distribution system insulated from ground may attain a high potential due to transient voltages caused by arcing static electricity or accidental contact with higher potential circuits. The transformer steps the voltage down from 35kv to 15kv as indicated by the numbers next to the transformer symbol. Laminated core power transformers.
